A climate almanac for the restless — charting the world's seasons so you arrive in the good weather, not the rain.
Search your destination and study its year-ring — the twelve-month clock in the reading card. Green means go, amber is fair, blue is rain, red is heat. Choose your window at a glance.
Dates already fixed? Press “Good this month?” and the map keeps only the regions in their prime, fading the rest to the margins. A shortlist appears from the whole world.
Climate, not forecast. Each place shows its long-run average for every month — the usual shape of its year, not a prediction for a date. Use it to pick a month, then check a live forecast before you book.
The map sorts every place into five plain buckets — go, fair, too cold, too wet, and too hot. Eighteen large countries with very different regional climates, like the US, Vietnam and Chile, are split into sub-climates so one national verdict never misleads.
Data. Monthly normals from NASA POWER, sampled at one representative city per place. “Rain” is the share of days with measurable rain; “heat” is the average daily high. Borders from Natural Earth; live El Niño / La Niña status from NOAA.
New regions, city-level detail, and seasonal travel notes — a few times a year. No spam.
